Title: Improvements in or relating to speed indicators
IPC: G01P3/64
Filed: 1918-03-08
Abstract: 138,373. Kennedy, C. J. H. Mackenzie-, and Clarke, T. W. K. March 8, 1918. Periodic - counter indicators. - Apparatus of the periodiccounter type has an arm or pin fixed, transversely to a clockdriven spindle, while the pointer is fixed to another and co-axial spindle which is moved axially relatively to the clock-driven spindle simultaneously with the stopping of the arm after a predetermined movement of the body the speed of which is desired, and this axial movement is adapted to cause the pointer to be rotated to take up the same angular position as then occupied by the arm. An arm b is fixed to a spindle c geared through a toothed wheel c<1> to a clock mechanism comprising a mainspring d attached to the spindle d<1>, a balance-wheel e, escapement-wheel f, and lever g. The indicating-pointer h is carried by a hollow spindle i arranged to slide over the end of the spindle c and in a bracket k. The end of the spindle i is formed as a double helical cam of opposite hands, which cam engages the arm b when the spindle i slides, and thus the pointer h is moved angularly to the extent to which the arm b has moved. The spindle c is normally vertical, and the spindle i is normally held in the uppermost position, against the influence of a spring n, by one arm of a bent lever m engaging under a collar i<1> and acted upon by a spring m<1>. The other arm of this lever is acted upon by an electro-magnet (not shown), energized at the end of a fixed number of revolutions of the shaft the speed of which is desired, and the spindle i thus released for movement by its spring. Pneumatic or mechanical means may be substituted for the electric means described above. To reset the arm b, the spindle c is movable endways against the spring p, and when the lever m is moved so that the spindle i has engaged the arm b and set the pointer h, further movement of the spindle c causes the arm b to engage a fixed cam q with two helices of the same hand, and these cause the arm b and spindle c to be returned to zero angularly and the spring d to be rewound. The pin i<2> on the spindle i engages the bracket k and the arm h remains in the angular position to which it has moved. To allow of rewinding the spring without affecting the escapement mechanism, the latter is connected to an elongated pinion d<2> through a wheel r, the spindle of which is journaled in a bracket s, which swings about the spindle f<1> of the escapement-wheel against the influence of a spring f<2>.

Abstract: 1,109,772. Cold separation of gas mixtures. MESSER GRIESHEIM G.m.b.H. 30 Jan., 1967 [5 Feb., 1966], No. 4473/67. Heading F4P. Cooling of the reflux condenser 9 of a hydrocarbon gas mixture rectification column 7 is effected at least in part by withdrawing liquid C 1  and C 2  hydrocarbons from the base of the column, expanding of a valve 16 and thereafter passing it through the condenser 9 thereby liquefying effluent gas which is then separated at 11 into liquid for use as reflux and into gas (mostly methane). The cold content of the latter is recovered in a last exchanger 5 traversed by feed gas mixture. Evaporated sump liquid is expanded at a valve 32 and is joined by any sump liquid not having traversed condenser 9 before being fed to a demethanizer column 21. Product methane gas withdrawn through a line 25 and warmed in exchanger 5 is recompressed at 27 and added to the methane gas from column 7, and the combined methane streams are returned to a natural gas main 1 downstream of the withdrawal point for the feed to the separating apparatus. In a modification a first portion of the feed mixture is workexpanded in a turbine (35), Fig. 2 (not shown), and remainder is expanded at a valve (39) before passing to the column 7.

Filed: 1934-02-12
Abstract: 433,152. Cigarette-making machines. WIX, A., 338, Goswell Road, and EDWARDS, W. F. M., 1, Kempsford Gardens, Earl's Court, both in London. Feb. 12, 1934, No. 4641. [Class 130] In forming cigarette filtertips, a length of material comprising layers of crÛpe paper, with or without intervening absorptive layers, is fed intermittently between rollers 2. Strips are severed by a knife 4 and moved transversely by a plunger 6 through a guide 7 on to a paper strip 5 to which paste has been applied at intervals by the mechanism 13. Blades 9 attached to a chain running over inclined sprockets 11 cover the strips during their passage below the tobacco hopper 14, the tobacco deposited on the blades being removed by a reciprocating device 16 provided with cutters 16a and a suction nozzle 16b. The strips 1, the intervening tobacco and the paper wrapper are then formed to the required cross-section in the rod-forming mechanism 18. In a modification the strips are applied to the paper as before, but the tobacco is supplied as a continuous rod from a superposed channel, and severed at intervals. A second modification is described in which a continuous rod of wrapped tipping is produced. The strips severed by the knife 4 are transferred end to end on to the paper 5 which runs in a deepening trough. A similarly-shaped guide presses the strips from above ; forwarding rollers penetrate the guide, and the partlyformed rod is then finished in the mechanism 18.

Title: Winding machine control system
IPC: B65H59/38
Filed: 1948-02-18
Abstract: 653,902. Winding yarn &c. AMERICAN VISCOSE CORPORATION. Feb. 18, 1948, No. 4763. Convention date, Dec. 19, 1944. [Classes 120(ii) and 120(iii)] [Also in Group XXXV] The take-up means of a yarn &c. winding machine having a continuous source of supply, is driven by an electric motor having a variable speed characteristic and at least one exciting winding, a reactance coil being arranged in series with an alternating- current supply line for controlling the current fed to the exciting winding, an element, e.g. a dancer roll, carried in a loop of the yarn &c. mov-. ing in response to tension variations to move a magnetic core within the reactance coil to control the motor speed. The yarn from supply 2 passes about the dancer roller 3, carried by a pivoted arm 15, on its way to the traverse guide 4 to be wound upon the package 5. This latter is driven by an A.C. motor 11 through pulleys 8, 9 and belt 10. A cam 17 rotates with the arm 15, as it rises and falls with increase or decrease in yarn tension, and attached to the cam 17 by a flexible strand 19 is a magnetic core 18 which moves up and down in a sleeve 23 in a reactance coil 24 connected up in series with a winding of the motor 11 and the A.C. supply lines 25. A spring 21 is also secured to the cam 17 which carries a tilting mercury switch 26 so that if the arm 15 drops to the limit stop 37, the switch 26 will open and stop the motor 11. A starting switch 27, spring- urged into the open position, enables the motor to be started at full line voltage, the coil 24 being short-circuited. As the package 5 builds, the roller 3 tends to lift thus lowering the core 18 into the reactance coil 24 and slowing up the motor. The core 18, which is attracted by the coil 24, and the cam 17, are preferably formed such that a gradual decrease in tension in the yarn is effected throughout the wind. In a modification, an adjustable counter-weighted arm is connected to the arm 15 so that the rate of decrease in tension may be further controlled. An adjustable projection 34 carried by the traverse frame 14 contacts a switch 33 and lights a lamp 35 when the package reaches a predetermined size. In an alternative construction, the master switch 26 may be operated by the projection 34 to switch off the motor 11 when the package is fully wound. If a direct current motor is used, a rectifier 38 is inserted in the circuit thereto. Specification 26235/04, [Class 120], is referred to.

Patent GB-402105-A (GB)
Title: Improvements in processes for the treatment of filaments, threads, fabrics and the like, of organic esters of cellulose
IPC: D01F2/28
Filed: 1932-02-19
Abstract: Filaments, threads, yarns, or the like, or fabrics containing the same, of organic esters of cellulose of high viscosity characteristics, are subjected to saponification.  The products have a relatively high tenacity and an affinity for cotton p  colours.  In the case of cellulose acetate, the viscosity as measured by the rate of flow of a 6 per cent. acetone solution against a standard of glycerine at 25 DEG  C. as 100, should exceed 30, and preferably is of the order of 50 or 200 or more.  The high viscosity esters may be obtained, for example, according to the process of Specification 207,562, [Class 2 (ii), Cellulose &c.]. The filaments may be produced by dry or wet spinning processes, preferably accompanied or followed by stretching.  Examples of suitable wet spinning processes are those of Specifications 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, and 378,858, and of stretching processes those of Specifications 277,089, 323,790, [both in Class 2 (ii), Cellulose &c.], and 370,430. Saponification may be carried out by means of solutions of caustic soda or caustic potash in aqueous or alcoholic media.  When caustic alkali is employed in high concentration it is preferable to have present also a buffer substance, e.g., sodium chloride, sodium acetate or a soap.  Saponification is conveniently carried out as a batch treatment.  For example, cakes of filaments &c. may be supported from the interior by means of a swift which is made expansible for insertion in the cake, the swift comprising an end plate perforated at the periphery with small holes for the insertion of a number of wires which after insertion in the interior of the cake may be expanded umbrella-fashion by means of a conical piece sliding on a shaft fitted to the end plate. Alternatively, a number of small segmental gauzes are fitted inside the cake, the gauzes being attached to each other in pairs by a spring distance piece.  The saponifying liquid is then circulated through the cake for the requisite time.  Other saponification methods specified are padding and spraying.  If desired, a wetting agent may be applied prior to saponification. The extent of saponification may vary from 5 to 20 per cent where the saponification is mainly superficial, up to substantially complete elimination of the ester groups.  If desired, the filaments &c., before or after saponification, may be subjected to treatment with shrinking agents to improve their extension, for example, by the process of Specification 380,504, 380,505, or 389,823.  In an example, yarn which has been dry spun from cellulose acetate having a viscosity of 146 is treated in hank or cake form by means of alcoholic solutions of caustic alkali in various concentrations and under various conditions of time, temperature, and quantity.  The Provisional Specifications refer also to Specifications 125,153, 313,404, 316,521, 318,468, [all in Class 2 (ii), Cellulose &c.], 371,461, and 400,996.
